After more or less a month from its release, the new OpenOffice 3.0 is receiving tons of positive comments. Anyway, this week, in our Freeware page, we have posted some brief notes abut three different extensions which are able to improve your effectivenss in office routines. First of all we have ooo2gd a simple menu bar which allows you to directly upload or download all kind of documents from Google Documents and Zoho. The second one is the Sun PDF Import Extension which has been created to allow minimal but useful changes to PDF documents. After few minutes we were able to make some interesting changes to a complex PDF documents with just a couple of clicks and export the result “into a hybrid PDF file, which is a PDF with the embedded source file asODF “. Last but not least we tested Sun Presentation Minimizer: an effective extensions which cuts the size of presentations reducing, for example, the image sizes. Using Sun Presentation Minimizer you will be able to simply and freely decide what kind of changes you want to make to your multimedia files contained in the presentations. To conclude it is necessary to focus your attention on the feature that also allows Sun Presentation Minimizer to work on Microsoft PowerPoint presentations.  In few words we think that these extensions are guaranteed to be 100% satisfactory!!
